Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most commonly used classes of capacitor, due to their low cost and good performance. The LNY2W123MSEJBN is an aluminum electrolytic capacitor in the excellent B series range. It is a polarized capacitor which means it has a strictly positive and negative terminal, with its anode being the positive side.

Application Fields

The LNY2W123MSEJBN is most commonly used in input and output filtering, and output hold-up applications. It is used in audio and video applications to reduce noise which could otherwise be picked up by the device, and it is also used in power supplies to ensure the output voltage is as smooth and steady as possible. It can also be used in power rectification circuits, and also for signal timing applications, as its capacitance is relatively low.

Working Principle

Aluminum electrolytic capacitors are made using an electrolyte solution and metal foil as the two electrodes, with a dielectric layer between them. This dielectric layer is made using an oxide which is formed when current is passed through the anode foil, causing it to act as an electrolyte. This forms a very thin oxide layer on the anode foil, which acts as the dielectric layer. The operating principle of aluminum electrolytic capacitors is based on the principle of electrostatic attraction. When electric current is applied to the capacitor, an electric field is established between the two conductive plates, and a static charge is built up on them. This charge is proportional to the applied voltage and capacitor\'s capacitance. When the applied voltage is removed, the static charge will stay on the capacitor until it has dissipated, allowing it to provide a charge even when no voltage is applied.

Conclusion

The LNY2W123MSEJBN is an excellent aluminum electrolytic capacitor which is perfect for low-noise filtering applications. Its small size and low capacitance make it ideal for signal timing applications, and its high-quality construction ensures that it will last for many years. Its wide range of applications mean that it can be used in a variety of different projects, and its low cost makes it an economical choice.
